Endeavour's payload bay with the Raphaello module and Canadarm 2

S100-E-5015 (20 April 2001) --- One of the crew members of STS-100 aimed a digital still camera through Endeavour's aft flight deck windows to record this image of the cargo bay, backdropped against a scene of black space and Earth's horizon. Housed in the bay, beyond the docking mechanism in the foreground, is the Italian Space Agency-provided Raffaello cargo module, which is carrying several tons of equipment for the Expedition Two crew and racks of hardware for installation in Destiny which will be used for scientific research in the future. Raffaello, which is the second of three such logistics modules, will be berthed to the ISS on April 23 so its contents can be transferred to the station throughout the course of docked operations. Also in the bay is the 57-foot-long Canadarm2, which will be mounted on the Destiny Laboratory for future station assembly work. Endeavour's Canadian-built Remote Manipulator System (RMS) arm can be seen in its berthed position on the port side of the payload bay.
